Plot paths of coefficients or log-likelihood contributions for `crch.boost`

models.

```
# S3 method for crch.boost
plot(x, loglik = FALSE,
standardize = TRUE, which = c("both", "location", "scale"),
mstop = NULL, coef.label = TRUE, col = NULL, …)
```

x

an object of class `"crch.boost"`

.

loglik

logical whether log-likelihood contribution shall be plotted instead of coefficient value.

standardize

logical whether coefficients shall be standardized.
Not used if `loglik = TRUE`

which

which coefficients: `"location"`

and `"scale"`

plots
only the coefficients for the location and scale part of the model
respectively. `"both"`

plots the coefficient paths of both parts in one
graph.

mstop

Stopping iteration for which a vertical line is plotted.
Possible choices are `"max"`

, `"aic"`

, `"bic"`

,
`"cv"`

, `"all"`

, or `"no"`

. Default is the stopping iteration
used for fitting.

coef.label

logical whether paths shall be labeled.

col

Color(s) for the paths. If `which="both"`

a vector of
two colors where the paths for the location are plotted in the first
color and for the scale in the second color.
